Description

Oleyl Phosphate (Mono- And Di- Ester Mixture) is a versatile nonionic surfactant derived from oleyl alcohol and phosphoric acid. This compound is valued for its excellent emulsifying, wetting, and antistatic properties, making it a critical performance additive in numerous formulations. It is primarily sought after by manufacturers in the personal care, textile, metalworking, and agrochemical industries for its ability to enhance product stability and functionality.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and conditioning agent in creams, lotions, and hair care products.
• Textile Processing: Used as a lubricant, antistatic agent, and emulsifier in fiber spinning and fabric finishing.
• Metalworking Fluids: Serves as an effective emulsifier and corrosion inhibitor in soluble oils and coolants.
• Agrochemicals: Functions as an adjuvant and emulsifier in pesticide and herbicide formulations to improve spray coverage and efficacy.
• Industrial Cleaners: Employed as a wetting and dispersing agent in heavy-duty degreasers and cleaning concentrates.
• Paper & Pulp Industry: Utilized as a defoamer and processing aid in paper coating and pulp production.
• Plastics & Polymers: Acts as an internal antistatic agent and lubricant in polymer processing.
• Leather Processing: Used as a fatliquoring agent to soften and condition leather.

Quality Control

Our Oleyl Phosphate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as ester distribution, acid value, and moisture content are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture, which may affect product quality.
